Animenewsnetwork - I can't recall when the “chuunibyou” phenomenon started cropping up in anime, but it's quickly become a favorite topic for more than one genre in the medium. It's a useful idea that can easily serve as a springboard for stories about the struggle to find a place in the world. While other shows have done a respectable job of examining chuunibyou from an insider's perspective, When Supernatural Battles Became Commonplace goes a step further.
